      This bug description is a result of investigating JAVA-4155. The code

      cursor.next(callback);
cachePostBatchResumeToken(cursor);

      cursor.tryNext(callback);
cachePostBatchResumeToken(cursor);

      in AsyncChangeStreamBatchCursor.java results in having a race condition: resumeToken may not yet be known when retrying the next/tryNext operation.
